Corrosion inhibition in mild steel by anodizing and the extract of Emblica Officinalis
Journal Title: Journal of Achievements in Materials and Manufacturing Engineering - Year 2016, Vol 78, Issue 1
Abstract
Purpose: Corrosion is the process of degradation of the materials due to its interactionwith the atmosphere. All materials are susceptible to corrosion. Among all other materialsmetals are the most widely used materials. Metals are widely used for their properties suchas high strength, ductility, thermal resistance and formability. So it is important to establishsuitable methods to inhibit the corrosion of such materials. In this paper the material mildsteel has been selected as it is one of the most commonly used material. The method usedfor corrosion inhibition is anodization followed by sealing using an ecofriendly corrosioninhibitor. The eco-friendly material that is tested in this paper is Emblica officinalis morecommonly called as Amla. The material is first anodized in a 50% NaOH solution at elevatedtemperatures and their corresponding corrosion inhibition is studied using weight lossmethod. Properties such as adhesion, heat resistance are also tested for the material. FTIRis used to identify the coating produced by anodizing and also for the identification of thefunctional bonds in the ecofriendly corrosion inhibitor.
